my 2penneth- astra g 1.4 /1.6 8 valve., i look after a couple of these for a couple of neighbours, and one of them has done 100k, just has regular servicing , and has just failed its mot on 2 bulbs............the other is mint out of its face, apart from the fact he smokes in it. i think there very good cars, and are becoming cheap as chips. failing that, get lucky with a mk2 polo breadvan.
